Last January, Paul Chambers was arrested under terror laws for this tweet:

"Crap! Robin Hood airport is closed. You've got a week and a bit to get your shit together, or I'm blowing the airport sky high!!"

He was detained, questioned and later charged with sending a "menacing" message. He lost two jobs and gained a criminal conviction for something which everyone, including those who arrested him, classed as "obviously a joke".

The High Court Appeal is set to go ahead in May 2011. As you can imagine, barristers and the High Court aren't cheap and this gig will raise money to pay Paul’s legal fees.

Live line up includes @stephenfry, @rufushound, @davidschneider, @ajhmurray, @glinner. Will this be the most tweeted from gig ever? Tickets £20-30.
